This 'don't bother to read whole texts' thing.
It's absolutely no bother to read a whole text. Easiest thing in the world, in fact, & I'd happily take a salary for doing it all day.
I'm quite good at reading out loud & most of my classes like it when I do; in fact, 'just reading' lessons are something I do as a treat or a lazy lesson - enjoyable for everyone in the room.
However, Eng Lit should be about critical engagement & analysis. The students need to respond to what they're reading, which requires detailed text analysis, annotation, discussion & the teaching of essay writing skills, & this squeezes the time available for 'bothering' to read in class.
There's a definite dilemma between 'read full texts, even if they are 500 pages long, it's important' & 'read a wide variety of genres & styles, even if it means you look at extracts rather than full texts some of the time'.
Neither is the perfect solution: but the problem of tacking full texts really, really, isn't that English teachers can't be arsed to read with their classes.
